A nurse is collecting data from a client about range-of-motion for various joints. Which of the following should the nurse identify as an example of a ball and socket joint?

Ankle

Shoulder

Knee

Metacarpophalangeal

Answer and Explanation

The Correct Answer is B

A. Ankle is incorrect. The ankle is a hinge joint, which allows for movement in one plane (up and down), not the multidirectional movement characteristic of a ball and socket joint.

B. Shoulder is correct. The shoulder joint is a ball and socket joint. This type of joint allows for movement in multiple directions, including flexion, extension, abduction, adduction, rotation, and circumduction.

C. Knee is incorrect. The knee is a hinge joint, allowing for flexion and extension but not the wide range of motion that a ball and socket joint offers.

D. Metacarpophalangeal is incorrect. The metacarpophalangeal joints (knuckles) are condyloid joints, which allow for movement in two planes but not the full rotational movement of a ball and socket joint.

Correct Answer is A

Explanation

A. Applies suction during catheter removal: This is correct. Suction should only be applied when the catheter is being inserted into the tracheostomy, not when it is being removed. Applying suction during removal can cause trauma to the airway and disrupt the patient's airway integrity.

B. Suctions for 30 seconds: Suctioning for 30 seconds is generally within the recommended limit for suctioning. Prolonged suctioning can lead to hypoxia and other complications, but 30 seconds is a safe duration for most patients.

C. Preoxygenates with 100% oxygen: This is correct practice. Preoxygenating the patient before suctioning is important to avoid hypoxia, especially in patients with respiratory concerns.

D. Auscultates breath sounds: This is good practice. Auscultating breath sounds before and after suctioning helps assess the patient's respiratory status and can guide the nurse in evaluating the need for suctioning.

A. "I'll take him back to the nursery, so you can get some rest." B. "If I turn him on his side, maybe he'll go back to sleep." C. "Babies need to cry soon after they are born to develop their lungs." D. "Let me show you how to swaddle and cuddle him, then you try."

Correct Answer is D

Explanation

A. Taking the newborn back to the nursery is incorrect. While rest is important for the mother, removing the baby does not help build her confidence or teach her how to respond to her infant’s needs. Supporting her in learning newborn care is more beneficial.

B. Turning the baby on his side to help him sleep is incorrect. The safest sleep position for a newborn is on the back, according to safe sleep guidelines. Additionally, this response does not address the mother's feelings of inadequacy.

C. Explaining that babies cry to develop their lungs is incorrect. While crying is normal for newborns, this response dismisses the client’s concern rather than providing reassurance and support.

D. Showing the mother how to swaddle and cuddle the baby, then letting her try is correct. This approach provides practical guidance and empowers the mother, helping her build confidence in her ability to care for her newborn.
